I get this error...

ORA-00936 Missing Expression???

when I execute this code (the parameters have values in them. i suspect it is a type thing)...

Dim sSQL As String = _
"UPDATE TBLICPMETHODS SET Frequency = @Frequency, " & _
"Calibration = @Calibration, QCValue = @QCVAlue" & _
" WHERE Frequency = '" & Session("EditFrequency") & "' AND MethodNumber = " & ddlMethods.SelectedValue

Dim connConnection As New OleDbConnection(Application("ERSconnectionStr"))

connConnection.Open()

Dim cmdCommand As New OleDbCommand(sSQL, connConnection)

Dim prmFrequency As OleDbParameter = _
New OleDbParameter("@Frequency", OleDbType.VarChar, 75)

cmdCommand.Parameters.Add(prmFrequency)

Dim prmCalibration As OleDbParameter = _

cmdCommand.Parameters.Add(prmCalibration)

Dim prmQCValue As OleDbParameter = _
New OleDbParameter("@QCValue", OleDbType.Double, 75)
prmQCValue.Value = CDbl(sQCValue)
